Description
Die Erfindung betrifft eine Windenergieanlage mit wenigstens einem Flettner-Rotor nach dem Oberbegriff des Hauptanspruches.The The invention relates to a wind energy plant with at least one Flettner rotor according to the preamble of the main claim.
Neben den bereits jetzt vielfach aufgebauten, an Flugzeugpropeller erinnernden Windenergierotoren sind in der Technik eine Anzahl anderer, teilweise mit sehr interessanten technischen Eigenschaften bekannte Rotoren bekannt. Diese unterscheiden sich neben dem Wirkungsgrad ganz erheblich in ihrem optischen Eindruck, so daß sie u.U. schon allein wegen des gefälligeren Eindrucks an manchen Standorten größere Akzeptanz als bisherige Konzepte haben können.Next the already constructed many times, reminiscent of aircraft propellers Wind energy motors are in the art a number of others, in part Rotors known with very interesting technical characteristics known. These differ considerably in addition to the efficiency in their visual impression, so that they u.U. because of it alone the more pleasing Impression in some locations greater acceptance than previous ones Concepts.
Zu nennen sind dabei insbesondere der Flettner-Rotor, wie auch der Darrieus-Rotor. Der Flettner-Rotor, der bisher als Antrieb für Segelschiffe benutzt wurde, nutzt beim Vortrieb von Schiffen den Magnuseffekt und kann aufgrund der Eigendrehung eines vertikalen Zylinders die Luftströmung ganz wesentlich umlenken. Dies ist bisher nur als Segelersatz aber durchaus mit Erfolg eingesetzt worden.To are in particular the Flettner rotor, as well as the Darrieus rotor. The Flettner rotor, which used to be the drive for sailing ships was, uses the propulsion of ships Magnuseffekt and can due to the rotation of a vertical cylinder, the air flow completely to divert substantially. This is so far only as a sail replacement but quite been used successfully.
Der
Darrieus-Rotor, wie er beispielsweise in dem
Die Erfindung hat sich zur Aufgabe gestellt, eine Windenergieanlage zu schaffen, die die Nachteile des üblichen Propellerprinzips vermeidet und in ihrer Effizienz gegenüber einem herkömmlichen Darrieus-Rotor gesteigert ist.The Invention has set itself the task of a wind turbine to create that avoids the disadvantages of the usual propeller principle and in terms of their efficiency a conventional one Darrieus rotor is increased.
Ein weiterer Vorteil ist, dass durch Anordnung der Generatoren im Bereich des Bodens statt auf einem hohen Turm die Wartungsmöglichkeiten einer derartigen Windenergieanlage erheblich verbessert sind und weniger Aufwand bei Turmkonstruktionen nötig ist.One Another advantage is that by arranging the generators in the area of the ground instead of on a high tower the maintenance possibilities Such a wind turbine are significantly improved and less effort is required in tower constructions.
Erfindungsgemäß wird die verbesserte Windenergieanlage sich mit wenigstens einem Darrieus-Rotor versehen, dessen Drehachse vertikal mit der eines Trägergestells im Wesentlichen zusammenfällt, wobei zwei Flettner-Rotoren außerhalb des Drehbereichs des Darrieus-Rotors jeweils gering in Luvrichtung versetzt im Wesentlichen neben dem Darrieus-Rotor angeordnet sind.According to the invention improved wind turbine with at least one Darrieus rotor provided, whose axis of rotation vertically with that of a support frame essentially coincides with two Flettner rotors outside the turning range of the Darrieus rotor each low in the windward direction offset substantially disposed adjacent to the Darrieus rotor.
Anders
als beispielsweise in der
Durch eine entsprechend mit Vertikalrillen oder auch mit golfballähnlichen Vertiefungen profilierte Oberfläche lässt sich der Effekt der Windlenkung durch die Flett ner-Rotoren deutlich vergrößern, so dass auf die eigentlichen energieerzeugenden Tragflächen des Darrieus-Rotors eine deutlich größere Windmenge auftrifft, als dies durch seine rein geometrischen Abmessungen möglich wäre.By a corresponding with vertical grooves or golfball-like Depressions profiled surface let yourself significantly increase the effect of the wind deflection by the Flett ner rotors, so that on the actual power-generating wings of the Darrieus rotor one significantly larger amount of wind impinges, as this would be possible by its purely geometric dimensions.
Gleichzeitig lässt sich der nutzbare Bereich der Windgeschwindigkeiten, in denen der Darrieus-Rotor betrieben werden kann, durch den Einsatz der Flettner-Rotoren günstig beeinflusst. Sollte einmal zuviel Wind sein, was bei herkömmlichen Windenergieanlagen zur Abschaltung führt, können die Flettner-Rotoren auch in entgegenlaufender Richtung zur Verminderung des auf den Darrieus-Rotor wirkenden Winds betrieben werden, was sich günstig auf die Gesamt-Energieproduktionszeit auswirkt.simultaneously let yourself the usable range of wind speeds in which the Darrieus rotor can be operated, favorably influenced by the use of Flettner rotors. Should be too much wind, what with conventional wind turbines leads to shutdown, can they Flettner rotors also in the opposite direction to the reduction of the wind acting on the Darrieus rotor, which is what favorable affects the overall energy production time.
